HMD9116T

Overview

The HMD9116T is a surface-mount LTCC band pass filter designed for wireless LAN applications. It operates with a center frequency of approximately 5.425 GHz and features a bandwidth of 1.05 GHz. The component utilizes a 0603 (1608 Metric) package size, ensuring compact integration into high-density circuit boards. It provides specific attenuation characteristics, including 30 dB rejection at 2400-2500 MHz and 25 dB rejection at 5150-5330 MHz, making it suitable for filtering out-of-band interference in 5 GHz ISM band communications.

Feature Summary

• LTCC construction for stable RF performance
• Optimized for 5 GHz Wireless LAN bands
• Compact 0603 surface mount footprint

Applications

• Wireless LAN modules operating in the 5 GHz band
• RF front-end filtering for IEEE 802.11a/n/ac devices
• ISM band communication systems requiring out-of-band rejection

Procurement Notes

Verify the exact center frequency specification against the manufacturer's official datasheet, as sources cite both 4900 MHz and 5.425 GHz. Confirm the package type is strictly 0603 (1608 Metric). Ensure compatibility with your PCB layout constraints regarding the small form factor. Cross-reference the attenuation values for 2.4 GHz and 5.15-5.33 GHz bands to confirm they meet your system's interference requirements before finalizing procurement.

Selection Notes

Select this component when a miniature RF filter is required for 5 GHz WLAN applications. The 0603 package allows for space-constrained designs. Verify that the specified insertion loss and rejection levels align with the system's link budget and regulatory mask requirements. Consider the LTCC technology benefits for thermal stability and reliability in consumer electronics environments.
